Can you SLI 2 different nVidia cards?

[TVisitor]

I'm about to replace my 8800GTX with a 260 core 216.

I don't currently have another sytsem to pop the 8800GTX into so it will sit idle, but I was wondering - can you SLI 2 different boards like this? My gut feeling is no, that they'd need to be identical.

No but you could use the 8800 for Physics. Not sure how useful that is yet though..

You can't SLI them for the purpose of increasing frame rate through AFR. You can go with 2 Nvidia cards and use one as a PhysX accelerator though. Personally I think an 8800GTX would be a terrible waste of resources in this capacity though.

There is some SLI flexibility between parts with different VRAM and slight differences in core (number of SPs) but performance scales to the lower of the two parts. A G80 and GT200 would most likely be unsupported due to too many differences.

Go ahead with the C216 (or wait a few weeks for the 55nm refresh) and then sell your 8800GTX on Ebay. They still fetch a pretty good price, ~$150 I believe was quoted a few weeks back.

I sold my 8800 GTX on ebay about two months ago for $150.

Will i be able to put 8800Gt and 9800GT in SLI? I heard that the later is just a refresh of 8800GT is that true?

Not without modifying or otherwise voiding the warranty of one of the cards. The driver checks for identical models when validating for SLI compatability.
